How to read this guide

GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Permit timeline

California SGIP - current category and budget check required

The 2026 SGIP rate table publishes $3.10/W for solar and $1.10/Wh for storage in applicable Residential Solar and Storage Equity categories. Household eligibility and live budget availability vary by category and program administrator; check the official Program Metrics tracker before relying on an incentive.

Utility and generation supplier

Utility

Southern California Edison (SCE)

SCE's own 'Incorporated Cities and Counties Served by SCE' fact sheet (updated 3/17/2025) explicitly lists 'Duarte' by name among the cities in its service area.

Sources & confidence

Confidence: High (0.9)

Source(s): Incorporated Cities and Counties Served by SCE

Generation supplier

Southern California Edison (SCE) (utility)

Clean Power Alliance's own homepage states it serves '38 communities across Los Angeles and Ventura counties' and names each one individually via its site's community directory; Duarte is not among the named communities. No other Los Angeles/Ventura County CCA serving Duarte was found, so Southern California Edison (SCE) is recorded as both the distribution and generation utility.
